Spine is an AI that lives on your desktop, not in a chat window. Answers land in your notes, and your notes float beside your work.
One hotkey and the chat bar slides in over whatever's open.
Ask, and it goes into your notes, not a thread you'll never scroll back to.
Close the app and your notes stay on screen, beside the slides or the code.
Every note is a plain markdown file on your computer. No lock-in.
